Genes affected

TRAF3IP1 (HGNC:17861): (TRAF3 interacting protein 1) The protein encoded by this gene interacts with TNF receptor-associated factor 3, tethering it to cytoskeletal microtubules. The encoded protein is also an inhibitor of the innate type I IFN response. Defects in this gene are a cause of Senior-Loken syndrome 9. [provided by RefSeq, Mar 2017]

This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 520 of the TRAF3IP1 protein (p.Met520Arg). This variant is present in population databases (rs750055952, gnomAD 0.006%). This missense change has been observed in individual(s) with Senior-Loken syndrome (PMID: 26487268). ClinVar contains an entry for this variant (Variation ID: 254147). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TRAF3IP1 protein function. Experimental studies have shown that this missense change affects TRAF3IP1 function (PMID: 26487268). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
